'What do you mean, I have to figure out the rules myself? How can I play this game if I don't know the rules?' Mao. The only game in which the rules of the game prohibit me from explaining the rules to you...Mao is a standard deck playing card game where the object is to get rid of all your cards. And this is the ONLY thing you are told about this game. You have to figure out the rest of the rules by yourself. Every time you break a rule, a penalty is called, and you are penalized a card. - BoardGameGeek
